The frames alternate in sequence, so the display receives a left eye frame, then a right eye frame, then a left eye frame, and so on. A frame sequential signal is a full resolution picture sent at 120 frames per second to the display. Frame sequential, also occasionally called page-flip, is in some ways the simplest of the 3D formats. There are other transmission formats as well, but we will focus on the four main formats for now.įrame sequential. We are not talking about the difference between passive polarized 3D glasses and active shutter 3D glasses (if you need more information about these display technologies, see our article "The 3D Renaissance").Īt last count, there are at least four stereoscopic 3D transmission formats currently in wide use, called frame sequential, frame packing, side-by-side, and checkerboard. By transmission format, we mean the 3D signal format used to transmit from your source-a computer, set-top box, game console, or Blu-ray player-to your projector. But what does this logo actually mean? In short: a 3D Ready projector will accept and display at least one stereoscopic 3D transmission format. To differentiate 3D projectors from their 2D brethren, there is usually a logo on the case declaring their 3D capability. What 3D signal sources will work with your 3D projector? What do you need to know to make sense of all of this stuff? After finishing this article, you will know exactly what 3D is and how it works.Įditor's note: This article has been updated to reflect the current state of 3D projection as of February 2012. Many 3D Ready projectors are available right now, as you read this article, but 3D is still a confusing subject. If you are like most consumers, you think " 3D Ready" means a projector is ready to display 3D in all its various forms.
